5850 Watercooling help

I have been doing a lot of thinking and would it be ok to just waterblock my 5850 card?

My CPU is cooled so well by my megahalems cooler with my 2 Xigmatek Black Line 120mm White LED push/pull setup. Its clocked @ 3.7ghz 1.40v and it idles @30c and underload max temp of 42c, i guess it would be silly to change that.

My 5850 is kinda loud when its fan speed hits the 50% mark so just want to know if its worth watercooling just a GPU or if there would be a better option like an after market cooler? im not to hot with these so not to sure what would go with my 5850 etc

Well I personally donth think you should water cool the gpu if you really dont want to. I ended up water cooling my 4890 for the fact that i hate the fan spooling up to 50% and like you said it gets way to loud for my taste. So I water cooled it and now everything is silent. The bonus was I was able to over clock it to 900Mhz Core clock and ram to 1000Mhz. Stock was 850Mhz & 975Mhz.

So imo I say do it so its get quite and you gives you the room for come OC. The cost might be a deterrent.

if it just the fan that annoys you then I would suggest an aftermarket air cooler but if you are looking for 1GHz core speed 24/7 then LC is the option I would go for as the voltgae needed will push the VRM temps through the roof for example mine hit 120C+ on stock but on water I barely hit 70C
